How To Identify The Safety Of Stainless Steel Vacuum Flask Materials?

Beautiful, long-lasting insulation, made of 304, 316 stainless steel... How to appreciate the good and bad of a stainless steel vacuum flask? The current stainless steel vacuum cup products are based on the national mandatory standard GB 4806 series standards and the nationally recommended standard GB/T 29606-2013 "Stainless Steel Vacuum Cup" to control product quality.

Focus on the following parameters:

Chemical safety index:

1. Liner material: The material of the inner liner of the stainless steel vacuum flask is the key to safety. Good stainless steel material is not only corrosion-resistant, high-strength, durable, easy to clean and disinfect, but also has a low amount of metal leaching.

2. Dissolution of heavy metals in the inner tank: If excessive arsenic, cadmium, lead, chromium, nickel, and other heavy metals are migrated from the stainless steel inner tank during use, the heavy metals accumulate in the human body, which will affect and damage the heart, liver, kidneys, and skin. The gastrointestinal, respiratory, and nervous systems, therefore, my country’s GB 4806.9-2016 "National Food Safety Standard for Food Contact Metals and Alloy Materials and Products" clearly stipulates the heavy metal content limit and monitoring conditions of stainless steel products.

3. The total migration and potassium permanganate consumption of the nozzle, straw, sealing parts, and inner coating: the total migration and potassium permanganate consumption respectively reflect the non-volatile content of food contact materials that can be transferred to food The content of sexual substances and soluble organic substances, these substances entering the human body may have adverse effects on human health.

Physical security indicators:

Including airtightness, peculiar smell, the strength of the thermos cup strap (sling), the color fastness of the strap, etc. It is well sealed and more thermally insulated; the abnormal smell affects the health of the human body or causes sensory discomfort; the color fastness of the strap (sling) is checked whether the accessory textile will Fading, reflecting the details of product quality.

Performance:

Thermal insulation performance and impact resistance, etc.

Thermal insulation performance is one of the important functions of a vacuum flask. The performance of thermal insulation is closely related to the production process, the vacuuming technology of the vacuum layer, and the airtightness. It is also related to the capacity of the container, whether there is an inner plug, the caliber, and the sealing result of the lid. Relationship; impact resistance test product durability. All of these test the design, material selection, and craftsmanship of the manufacturer, and reflect the quality of the product.

Label identification:

The label identification information guides consumers to purchase and use it correctly and is also a reflection of the added value of the product, usually including labels, certificates, instructions for use, etc. Wearing a thermos cup with well-made and complete information labels, the quality will not be bad, because the small label contains university questions. Generally, a good thermos mug label needs to convey at least the following information to consumers: product information, manufacturer (or distributor) information, safety compliance information, use precautions, maintenance information, etc.
